Description

Technical Field

[0001] The utility model relates to the technical field of electrical accessories, and particularly relates to a connecting buckle for a handle, a handle mounting structure and an electrical appliance. Background Art

[0002] There is a prior handle mounting structure including a handle, two connecting buckles, a mounting body and screws. Holes are drilled at the extended ends of the handle. The connecting buckle includes a top wall and a peripheral wall extending downward from the edge of the top wall and shielding on three sides while being open on one side. The lower edge of the peripheral wall of the connecting buckle abuts against the outer surface of the mounting body. The extended end of the handle is inserted between the top wall and the mounting body from the side opening of the peripheral wall. The screw passes through the first through hole of the mounting body and the second through hole of the extended end of the handle and then is locked with the screw hole of the connecting buckle, so that the extended ends of the handle are fixed to the outside of the mounting body and protected.

[0003] Based on the above mounting structure, there is another prior handle mounting structure. A positioning hole is drilled in the mounting body, and a protruding positioning post is provided on the connecting buckle to facilitate hole positioning before screwing, reducing the assembly difficulty. Although the cooperation of the positioning post and the positioning hole aligns the through hole of the connecting body with the screw hole, the elastic force of the handle and the axial force generated during the installation of the screw will push the connecting buckle and separate the positioning post from the positioning hole, resulting in positioning failure.

[0004] In addition, although the positioning post and the positioning hole are provided to align the through hole of the connecting body with the screw hole of the connecting buckle, the handle is movable and the holes drilled at its extended ends are shielded by the mounting body and the connecting buckle on both sides, and there is still a certain operation difficulty when driving the screw. Therefore, this kind of handle mounting structure also selects to integrally form the handle and the connecting buckle to eliminate the handle perforation positioning process. However, in this way, the connecting buckle and the handle cannot be made of different materials respectively, sacrificing their respective performances, such as the weakening of the strength of the connecting buckle and the decline of the feel of the handle. Summary of the Utility Model

[0005] The first object of the utility model is to provide a connecting buckle for reducing the assembly difficulty of a handle.

[0006] The second object of the utility model is to provide a handle mounting structure for reducing the assembly difficulty of a handle, in which the connecting buckle and the handle are separately provided while maintaining their respective performances.

[0007] The third object of the utility model is to provide an electrical appliance for reducing the assembly difficulty of a handle.

[0008] The connecting buckle provided by the first object of the present utility model includes a top wall, a peripheral wall, and a connecting structure. The inner periphery of the peripheral wall forms an installation position. The peripheral wall is provided with a notch communicating with the installation position. The top wall is connected to the first height end of the peripheral wall and shields the installation position. The inner periphery of the second height end of the peripheral wall forms an opening communicating with the installation position. The opening and the notch communicate to form an installation opening for the installation position. The connecting structure is arranged in the installation position and is connected to the top wall and / or the peripheral wall. A screw hole facing the opening is arranged on the connecting structure. The connecting structure includes a central column, and the screw hole is arranged on the central column. The central column is used for inserting and mating with the first through hole of the handle. The connecting buckle further includes a spring buckle. The spring buckle is connected to the second height end. The spring buckle includes a spring arm and an inverted buckle protrusion. The spring arm extends along the height direction of the peripheral wall and in a direction away from the top wall. The inverted buckle protrusion protrudes from the elastic free end of the spring arm at an angle with the spring arm. At least two spring buckles are arranged at different positions on the outer periphery of the installation position.

[0009] As can be seen from the above solution, the present utility model adds a central column to the connecting buckle. The central column can be pre-inserted into the first through hole of the handle to position the handle first. A protruding spring buckle is arranged at the bottom end of the peripheral wall of the connecting buckle. Correspondingly, a buckle position is arranged on the installation main body. After the connecting buckle is pressed and the spring buckle and the buckle position are buckled, the pre-installation effect is achieved. The screw hole of the connecting buckle is aligned with the second through hole of the installation main body. Since the connecting buckle is tightly buckled on the buckle position, during the process of driving the screw, the elastic force of the handle and the axial force generated during the process of installing the screw will not cause the connecting buckle to retreat and become loose. The process of driving the screw is more labor-saving. Therefore, the connecting buckle of the present utility model reduces the assembly difficulty of the handle, and the connecting buckle and the handle are kept separately arranged and separately selected materials to maintain their respective performances.

[0010] A further solution is that the spring buckle includes two axially symmetric and spaced-apart spring arms, and the inverted buckle protrusions on the two spring arms protrude back to back.

[0011] As can be seen from the above, in this setting, the positions of the spring buckle and the buckle position are symmetric, and the force is more uniform, avoiding damage and failure of the spring buckle caused by local stress, and improving the reliability of the connecting buckle.

[0012] A further solution is that the spring buckle further includes a reinforcing rib. The reinforcing rib includes a base portion and two rib portions extending separately from the base portion. The base portion is connected between the roots of the two symmetrically arranged spring arms. The two rib portions are respectively attached to the two spring arms and extend to the elastic free ends of the spring arms.

[0013] As can be seen from the above, this setting improves the strength of the spring buckle, further improving the durability and reliability of the connecting buckle.

[0014] Another further solution is that the connecting structure includes a seat body. The connecting buckle further includes a reinforcing rib network. The reinforcing rib network is connected between the top wall, the peripheral wall and the seat body. The top wall, the reinforcing rib network, the seat body and the central column are connected in sequence along the height direction.

[0015] As can be seen from the above, the reinforcing rib network includes rib plates that are interconnected vertically and horizontally. The reinforcing rib network can not only strengthen the connection between the top wall, the peripheral wall, and the connecting structure, but also, as a lifting structure, set the height of the central column to a more appropriate position by using the height of the reinforcing rib network. As a lifting structure, the reinforcing rib network has many hollow positions and is relatively light in weight. Therefore, the setting of the reinforcing rib network will not have a great impact on the weight of the connecting buckle.

[0016] A further solution is that the base body includes an end face, and the central column is connected to the end face; the reinforcing rib network includes inclined rib plates, and the inclined rib plates include a top surface facing the installation opening. From the base body to the notch, the top surface gradually approaches the top wall.

[0017] As can be seen from the above, this setting takes into account the actual use state of the handle. When the handle is lifted and bent, the handle will extend obliquely upward from the central column to the notch on the peripheral wall. Without a transition design, the handle will be subjected to local stress and is prone to damage. Therefore, the present utility model is provided with inclined rib plates, and the extension trend of the top surface of the inclined rib plates is consistent with the extension trend of the handle in the use state, avoiding damage to the handle and improving the service life of the product.

[0018] Another further solution is that the peripheral wall is in the shape of a square box with one side open, and the peripheral wall includes three wall bodies that are sequentially bent and connected and face different directions, and at least one elastic buckle is connected to each wall body.

[0019] As can be seen from the above, in this setting, the force borne by the connecting buckle is dispersed to more elastic buckle positions, further avoiding excessive local stress and obtaining a better positioning effect.

[0020] Another further solution is that the peripheral wall is provided with a converging wall portion extending to the second height end, and along the direction away from the top wall, the outer peripheral dimension of the converging wall portion gradually decreases to the second height end.

[0021] As can be seen from the above, when the installation main body is provided with a concave position that cooperates with the peripheral wall, the setting of the converging wall portion makes it easier for the peripheral wall to be inserted into the concave position, reducing the assembly difficulty.

[0022] The handle installation structure provided by the second object of the present utility model includes a handle, a connecting buckle, an installation main body, and a screw. First through holes are provided at the extending ends of the handle, a second through hole is provided in the installation main body, and the handle is arranged between the connecting buckle and the installation main body; the connecting buckle adopts the above-mentioned connecting buckle, and the installation main body is provided with a buckle position that opens along the height direction on the outer periphery of the second through hole; the extending end portion of the handle is placed in the installation position, the central column passes through the first through hole, the elastic buckle is buckled with the buckle position, and the screw passes through the second through hole and then cooperates with the screw hole.

[0023] A further solution is that the installation main body is provided with a concave position, and both the second through hole and the buckle position are provided on the bottom surface of the concave position; the peripheral wall is placed in the concave position.

[0024] As can be seen from the above, in this setting, not only can a good hole positioning effect be achieved by using the peripheral wall and the concave position, but when the handle is in use, a part of the acting force between the connecting buckle and the connecting body can act on the peripheral wall, avoiding all the acting forces from concentrating on the spring buckle, and further improving the durability and reliability of the connecting buckle.

[0025] The electrical appliance provided by the third object of the present utility model includes the above-mentioned handle mounting structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The First Embodiment of the Handle Mounting Structure

[0036] Referring to Figures 1 to 3 , the electrical appliance in this embodiment is a portable clothes dryer, and the clothes dryer includes a handle mounting structure. The handle mounting structure includes a mounting body 1, a handle 2, two connecting buckles 3, and two screws 4. Among them, the mounting body 1 is the outer shell of the clothes dryer.

[0037] The wall panel of the main body 1 is provided with a recess 10 that is recessed from its surface along the x-axis direction shown in the figure. The inner contour of the recess 10 matches the outer contour of the connecting buckle 3. A second through hole 110 is provided at the center of the bottom surface 11 of the recess 10. Three buckle positions 12 are provided at the outer edge of the bottom surface 11 close to the inner wall surface of the recess 10. The three buckle positions 12 are located at different positions on the outer periphery of the second through hole 110. The three buckle positions 12 and the second through hole 110 are all open towards the entrance direction of the recess 10, that is, towards the x-axis direction.

[0038] Two extending ends 21 of the handle 2, that is, the two extending ends of the handle 2, are both provided with a first through hole 20. A central column 332 is provided on the connecting buckle 3, and a screw hole 333 is provided on the central column 332. The extending end 21 of the handle 2 is arranged between the connecting buckle 3 and the mounting main body 1. The extending end 21 is sleeved outside the central column 332, that is, the central column 332 passes through the first through hole 110, and then the screw 4 passes through the second through hole 110 and cooperates with the screw hole 333.

[0039] See Figures 4 to 6 , the connecting buckle 3 includes a top wall 31, a peripheral wall 32, a connecting structure 33, a reinforcing rib network 34 and a spring buckle 35.

[0040] The peripheral wall 32 is in the shape of a square box with one side open. The peripheral wall 32 includes three wall bodies 321 that are sequentially bent and connected and face different directions. The inner periphery of the peripheral wall 32 forms a mounting position 30. A notch 320 that communicates with the mounting position 30 is formed at the open side of the peripheral wall 32. The opening direction of the notch 320 is the same as the extending direction of the top wall 31. The opening direction of the notch 320 is as shown in the Figure 5 y-axis direction of.

[0041] Figure 4 As shown, the x-axis direction is the height direction of the peripheral wall 32. The x-axis direction is perpendicular to the y-axis direction. In the height direction, the peripheral wall 32 includes a first height end 3201 and a second height end 3202 that are oppositely arranged. The top wall 31 is connected to the first height end 3201 of the peripheral wall 32 and blocks the mounting position 30. An opening 300 that communicates with the mounting position 30 along the z-axis direction is formed at the inner periphery of the second height end 3202 of the peripheral wall 32. The opening 300 and the notch 320 communicate with each other to form the mounting opening of the mounting position 30.

[0042] In addition, see Figure 4 , the peripheral wall 32 is provided with a converging wall portion 322 that extends to the second height end 3202. Along the direction away from the top wall 31 shown in the negative x-axis direction in the figure, the outer peripheral dimension of the converging wall portion 322 gradually decreases to the second height end 3202. In this embodiment, the outer peripheral dimension of the converging wall portion 322 refers to the width and length of the outer wall surface of the converging wall portion 322.

[0043] The reinforcing rib network 34 includes rib plates that are crisscrossed and connected. The reinforcing rib network 34 is disposed within the installation position 30, protrudes and covers the inner surface of the top wall 31, and the rib plates in different directions thereof all extend to the inner wall surface of the peripheral wall 32, that is, the reinforcing rib network 34 is connected between the top wall 31 and the peripheral wall 32.

[0044] The connecting structure 33 is connected to the reinforcing rib network 34 and is located at the center of the installation position 30. The connecting structure 33 includes a base body 331 and a central column 332. The reinforcing rib network 34 is connected among the top wall 31, the peripheral wall 32, and the base body 331. The top wall 31, the reinforcing rib network 34, the base body 331, and the central column 332 are sequentially connected along the height direction of the peripheral wall 32.

[0045] The central column 332 is used for insertion and mating with the first through hole 20 of the handle 2. The axial direction of the central column 332 is consistent with the height direction of the peripheral wall 32. The height direction of the peripheral wall 32 is also the pressing and installation direction of the connecting buckle 3 and the direction in which the connecting buckle 3 faces the installation main body 1. A screw hole 333 facing the opening 300 is provided at the extending end of the central column 332.

[0046] The reinforcing rib network 34 has many hollow positions and is relatively light in weight. Therefore, the setting of the reinforcing rib network 34 will not have a great impact on the weight of the connecting buckle 3. The reinforcing rib network 34 can not only reinforce the connection among the top wall 31, the peripheral wall 32, and the connecting structure 33, but also, as a lifting structure, set the height of the central column 332 to a more appropriate position by using the height of the reinforcing rib network 34. In this embodiment, the central column 332 protrudes beyond the second height end 3202 of the peripheral wall 32.

[0047] Further, the base body 331 includes an end face 3311, and the central column 332 is connected to the end face 3311. The reinforcing rib network 34 includes four inclined rib plates 341 that are parallel to each other and arranged at intervals. The inclined rib plates 341 include a top surface 3411 facing the installation opening. From the base body 331 to the notch 320, the top surface 3411 extends obliquely and gradually approaches the top wall 31. Two of the inclined rib plates 341 are connected to the base body 331, and the top surfaces 3411 of these two inclined rib plates 341 start from the end face 3311. The highest points of the top surfaces 3411 of the other two inclined rib plates 341 are closer to the top wall 31 than the end face 3311.

[0048] See Figure 5 and Figure 6, a snap button 35 is connected to each wall body 321 of the peripheral wall 32, and the snap button 35 is connected to the second height end 3202. The snap button 35 includes a snap arm 351, an inverted buckle protrusion 352 and a reinforcing rib. The arm 351 extends along the height direction of the peripheral wall 32 and in the direction away from the top wall 31. The inverted buckle protrusion 352 protrudes from the elastic free end of the snap arm 351 at an angle with the snap arm 351. Each snap button 35 includes two symmetrically arranged and spaced snap arms 351, and the inverted buckle protrusions 352 on the two snap arms 351 protrude back to back with each other.

[0049] The reinforcing rib includes a base portion 353 and two rib portions 354 extending separately from the base portion 353. The base portion 353 is connected between the roots of the two symmetrically arranged snap arms 351. The two rib portions 354 are respectively attached to the two snap arms 351 and extend to the elastic free ends of the snap arms 351.

[0050] Combined with Figure 3 and Figure 7 , the extended end portion 21 of the handle 2 is placed in the installation position 30 from the opening 300. The central column 332 is inserted through the first through hole 20, and the handle 2 extends out from the notch 320. The connecting buckle 3 is pressed and installed into the concave portion 10 of the installation main body 1 along the x-axis direction. The peripheral wall 32 is placed into the concave portion 10. The three snap buttons 35 are respectively engaged with the three buckling positions 12. At this time, the screw hole 333 is aligned with the second through hole 110 of the installation main body 1, and the screw 4 can pass through the second through hole 110 and cooperate with the screw hole 333 to be tightened. During the process, the arrangement of the converging wall portion 322 makes the peripheral wall 32 easier to be installed into the concave portion 10, reducing the assembly difficulty.

[0051] Since the connecting buckle 3 is tightly fastened to the buckling position 12, during the process of driving the screw 4, the self-elastic force of the handle 2 and the axial thrust generated during the installation of the screw 4 will not cause the connecting buckle 3 to retreat and become loose. The process of driving the screw 4 is more labor-saving. Therefore, the connecting buckle 3 of the present utility model reduces the assembly difficulty of the handle 2, and the connecting buckle 3 and the handle 2 are respectively arranged and made of different materials to maintain their respective performances.

[0052] Furthermore, referring to Figure 7 , the present utility model takes into account the actual use state of the handle 2. When the handle 2 is lifted and bent, the handle 2 will extend obliquely upward from the central column 332 to the notch 320 of the peripheral wall 32. The extending trend of the top surface 3411 of the inclined rib plate 341 is consistent with the extending trend of the handle 2 in the use state, avoiding excessive local stress from damaging the handle 2 and improving the service life of the product.

[0053] Second and third embodiments of the handle installation structure

[0054] Referring to Figure 8 and Figure 9, the illustrated x-axis direction is the pressing and installation direction of the connecting buckle and the direction of the connecting buckle relative to the installation body. The height of the connecting buckle and the peripheral wall refers to the dimension in the x-axis direction. Even if the extending directions of the peripheral wall 51 in the second embodiment and the peripheral wall 52 in the third embodiment are both inclined to the illustrated x-axis direction, the x-axis direction is still taken as the height direction of the peripheral wall 51 and the peripheral wall 52.

[0055] In other embodiments, the snap buckle only includes one elastic arm and the reverse buckle protrusion on the elastic arm.

[0056] In other embodiments, two snap buckles can be provided on the peripheral wall, or four or more snap buckles can be provided.

[0057] In other embodiments, the reinforcing rib network is not provided, and the connecting structure is directly connected to the top wall, and / or the connecting structure is directly connected to the peripheral wall.

[0058] The electrical appliance of the present utility model can also be a small electrical appliance such as a fan, a dehumidifier, a humidifier or an electric heater.

[0059] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
